What is this on my BN Pleco?

Fungal infections don't have tentacles....this reminds me of the movie Alien

? True ! A pure gem !
So what ? Colin said "It's not a creature from the black lagoon or a parasite."

Something out of all our nightmares.

Tentacles ? Where ? Not on the newer pics.

In the original video, it looks like tentacles burst out of it.

The tentacles show really well on the original video. In the still pics. everything just looks like a fungal infection and they don’t show the full scope of this thing. I think this may not be a ‘parasite’ - as in an organism which has a specific host which it exploits - but just something looking for somewhere to live which happened to land on on an unfortunate passing fish rather than a nice rock.

I would try salt as ColinT prescribes. But I have in a past life knocked things like that out with formalin, you would need to check dosage rates. I think about a 30 second bath in a weak solution.

My bn pleco can’t handle anymore than just a tinge of salt.

I think there's a confusion with its large and numerous barbels as video is rather blurred.
So please @JamieTYV is there any kind of tentacles on your fish ?

There's no confusion... Rewatch the original video. There aren't "tentacles", but strange appendages that stretch out.

That's what I've always been told : never salted bath for scaleless fishes.

It's definitely another organism that has latched onto the fish....poor pleco
@Colin_T , did you watch the GIF/video in the very first post?

 

[Avel1896]

Let's wait for @JamieTYV answer.

Let's wait for @JamieTYV answer.

The term "tentacles" was being used very loosely. Not "tentacles" like an octopus. They're just weird... Things.

Animated appendages....

I’ve done it before in half doses with my cories but when I tried with my pleco, he went nuts! I could tell it was hurting him so I had to drain a 55G tank down about 80%. Poor guy.
